There are various risks associated with the confidentiality of written of electronic communications. When sending emails it is vitally important that you enter the exact email address otherwise the email may be sent to the wrong recipient.

It is true that in data communications the sending device is usually a computer. The main components are transmitter, receiver & antenna and every communication device must have all these three components
Sending computer system and equipment ( sending unit transmits a signal)to a modem ( that can perform many tasks)telecommunications ( medium is any material that carries a electronic signal to support communications )to another modem ( connected to the receiving device )the receiving unit ( receives the signal )the process is reversed.
DEModulating
A type of communications device that connects a communications channel to a sending or receiving device is a modem. Modems modulate and demodulate signals for transmission over various types of media, such as telephone lines or cable systems. They enable digital devices to communicate with each other by converting digital data into analog signals and vice versa.
Phantom power is a method used in audio equipment to provide power to microphones that require it to function. It works by sending a direct current voltage through the same cables that transmit the audio signal, allowing the microphone to operate without needing its own power source.
A phantom power supply is a method of providing power to certain types of microphones that require it to function. It works by sending a low-voltage electrical current through the microphone cable, allowing the microphone to operate without needing its own power source.
